The idiom is listed in the lexicon, because it's meaning cannot be inferred from it's constituents. And the idiom is a single semantic unit. Thus the idiom is inserted to the syntax in the quality of a word. But the idiom is not always inserted to the syntax as a word. In the process generating the sentence, we can recognize the categorial property of the idiom that it is formally equal to the syntactic phrase. Then each of the constituents of the idiom can be inserted to the syntax. This is why the syntactic operation(as modification, topicalization, relativization, etc) can be applied to the constituent of the idiom. In this respect the idiom is a flexible construction as the listeme of a lexicon. The flexible property of the idiom is related to the dynamicity of a lexicon. The formal or semantic transformation of the idiom is the good example to show the dynamicity of a lexicon.

The aim of this paper is to elucidate ancient Chinese philosophy and linguistics through the concept of the Dao. Ancient Chinese thought had developed together with ancient Chinese theories of language and the linguistic features of Classical Chinese. The concept of the Dao served as an intermediary among them. The Dao which ancient Chinese philosophers sought for has several characteristics: ethical normativity, wholeness, dynamicity, non-reducibility. Linguistic studies also revealed them. The following linguistic features of Classical Chinese are the cause and/or the effect of such Dao-based philosophy and linguistics: No explicit subject-predicate sentential structure, no parts of speech, heavy reliance on the word order and context for meaning determination, no explicit distinction between compound words and a sentence, the pictographic or the ideographic features of Chinese graphs, and non-existence of a copula.

Kademlia와 같은 DHT(Distributed Hash Table) 네트워크는 참여노드들이 네트워크 토폴로지 상에서 자신의 위치를 자율적으로 결정하는 구조를 가지고 있으며 이를 악용한 ID 매핑 공격에 매우 취약하다. 그 결과 DHT 네트워크에서는 eclipse, DRDoS, 봇넷 은닉통신 등의 보안 문제가 지속적으로 발생되고 있다. 본 논문에서는 ID 매핑 공격을 방지하기 위한 비 자율적 노드 위치 결정 방법을 제안하고 NAT 호환성, 공격 저항성, 네트워크 다양성의 세 가지 측면의 분석을 통해 타 방어기법들과 비교를 수행하였다. 분석결과, 제안된 방법은 타 방어기법과 동등한 수준의 공격 저항성을 나타냄과 동시에 타 방어기법이 갖는 단점인 NAT 호환성과 네트워크 다양성 문제를 극복할 수 있음을 확인하였다.

This study considers the correlation between model pose and clothes in Patrick Demarchelier's fashion photos as well as expression characteristics. The conclusions of the study are as follows. The type of model pose in Patrick Demarchelier's fashion photos can be categorized into five types: maximized type of upper and lower body part, minimized type of upper and lower body part, maximized type of upper body and minimized type of lower body part, minimized type of upper body and maximized type of lower body part, basic type of upper and lower body part. In case of having examined the correlation between body movement and costume, the clothes in the model pose included in the maximization of the body were formed mainstream by silhouette, which was formed by decorative elements or full drapery. In the model poses included in the reduction of the body, the costume tended to expose many parts of the body to provide a simple or structural silhouette form. The costume was expressed in colorful form and poses assumed without body movements. The expression characteristics of the model poses in Patrick Demarchelier's fashion photos were sensuality, dynamicity, and simplicity. First, sensuality was expressed as feminine sensuality accompanying an erotic mood by naturally emphasizing a woman's breast or leg by reducing the body. Second, dynamicity provided a vividness to the image as if directly living and moving by highlighting the rhythmic aspect of the body. Simplicity aroused the effect of paying attention to clothes or other incidental elements rather than the image expressed by the body of a model by excluding body movement.

Brain organoids are an exciting new technology with the potential to significantly change our understanding of the development and disorders of the human brain. With step-by-step differentiation protocols, three-dimensional neural tissues are self-organized from pluripotent stem cells, and recapitulate the major millstones of human brain development in vitro. Recent studies have shown that brain organoids can mimic the spatiotemporal dynamicity of neurogenesis, the formation of regional neural circuitry, and the integration of glial cells into a neural network. This suggests that brain organoids could serve as a representative model system to study the human brain. In this review, we will overview the development of brain organoid technology, its current progress and applications, and future prospects of this technology.

The mobile network allows redundant transmission via disjoint paths to support high-reliability communication (e.g., ultrareliable and low-latency communications [URLLC]). Although redundant transmission can improve communication reliability, it also increases network costs (e.g., traffic and control overhead). In this study, we propose a reliability-guaranteed multipath allocation algorithm (RG-MAA) that allocates appropriate paths by considering the path setup time and dynamicity of the reliability paths. We develop an optimization problem using a constrained Markov decision process (CMDP) to minimize network costs while ensuring the required communication reliability. The evaluation results show that RG-MAA can reduce network costs by up to 30% compared with the scheme that uses all possible paths while ensuring the required communication reliability.

The emerging of cloud data sharing can create great values, especially in multi-cloud environments. However, "data island" between different cloud service providers (CSPs) has drawn trust problem in data sharing, causing contradictions with the increasing sharing need of cloud data users. And how to ensure the data value for both data owner and data user before sharing, is another challenge limiting massive data sharing in the multi-cloud environments. To solve the problems above, we propose a Uniform Encoding and Parsing Framework (UEPF) with blockchain to support trustworthy and valuable data sharing. We design namespace-based unique identifier pair to support data description corresponding with data in multi-cloud, and build a blockchain-based data encoding protocol to manage the metadata with identifier pair in the blockchain ledger. To share data in multi-cloud, we build a data parsing protocol with smart contract to query and get the sharing cloud data efficiently. We also build identifier updating protocol to satisfy the dynamicity of data, and data check protocol to ensure the validity of data. Theoretical analysis and experiment results show that UEPF is pretty efficient.

Online education, commonly referred to as distance education, has developed rapidly. However, it is questionable whether such distance education has been applied to various educational fields and has achieved satisfactory results in terms of learning effect. One of the reasons for not maximizing the benefits of distance education is non-dynamicity in the production and application of educational content. Educational contents production is made up of collaborative work between the instructor who is the contents expert and the developer who is the production expert. For this reason, existing researches have also concentrated on the improvement of each educational effect. In this paper, we propose to replace a production expert from a developer to an instructor. At this time, the important point is that the educational contents produced by the instructor, who is a development non-expert, should still be able to be maintained with high-quality contents utilizing the characteristics of the web. For this purpose, the production system was developed based on open source to maintain the quality similar to the educational contents developed by the production expert. This will increase the effectiveness of education by applying the developed Smart-Blended Learning System to various educational sites.

Pervasive computing is characterized by a key characteristic that affects the operating environment of services and users. It places more emphasis on dynamic environments where available resources continuously vary without prior knowledge of their availability, while in static environments the services provided to users are determined in advance. At the same time, Cloud computing paradigm introduced flexibility of use according to the user's profile and needs. In this paper, we aimed to provide Context-Aware Transactional Service applications with solutions so that it can be integrated and invoked like any service in the digital ecosystem. Being able to compose is not enough, each service and application must be able to offer a well-defined behavior. This behavior must be controlled to meet the dynamicity and adaptability necessary for the new user's requirements. The motivation in this paper is to offer design patterns that will provide a maximum of automatism in order to guarantee short reaction times and minimal human intervention. Our proposal includes a cloud service model by developing a PaaS service that allows CATS adaptation. A new specification for the validation of CATS model has been also introduced using the ACTA formalism.
